Description

Technical Field

[0001] The present application relates to the field of sensor technology, and in particular to an encoder, a motor and automation equipment. Background Art

[0002] An encoder is an angle measuring device based on converting light signals into electrical signals. It converts the periodic changes of light into periodic electrical signals, and converts these changes into usable digital or analog signals through circuit processing. Photoelectric encoders have good anti-interference, high precision, high stability and other characteristics, and are widely used in various places where angle measurement is required.

[0003] In related technologies, encoders often use an integrated structure with tightly coupled functional modules, which limits the flexibility of encoders to a certain extent. Once user needs change, such as the need to adjust or add additional functions, the entire encoder often needs to be redesigned, which not only increases production costs, but also prolongs product delivery cycles, making it difficult to meet rapidly changing market demands. Utility Model Content

[0004] In order to solve the problem that the encoder in the related art cannot be flexibly adjusted, resulting in difficulty in meeting the rapidly changing market demand;

[0005] The first aspect of the present application is to provide an encoder;

[0006] The second aspect of the present application is to provide a motor;

[0007] The third aspect of the present application is to provide an automation device.

[0008] In view of this, according to the first aspect of the present application, an encoder is proposed, comprising: a shell, comprising at least three supports, which are stacked in sequence; the support has a first end, a second end and a accommodating cavity; the first end and the second end are relatively arranged along the stacking direction of the support, and the first end is recessed inward to form an accommodating cavity; the second end is provided with a spindle hole that penetrates the support along the stacking direction; the spindle is inserted into the spindle hole; a measuring component, comprising a code disk, a light source and a photosensitive chip, the code disk, the light source and the photosensitive chip are respectively arranged in three accommodating cavities, and the code disk and the spindle are coaxially connected, the light source is arranged on one side of the code disk, and the photosensitive chip is arranged on the side of the code disk away from the light source.

[0009] In the above technical solution, at least three supports are stacked in sequence to form a shell, and the code disk, light source and photosensitive chip are respectively arranged on the three supports, that is, a modular installation method, so that the entire encoder can be installed in the form of loose parts. This installation method not only simplifies the assembly process of the encoder, but also makes the encoder more convenient during manufacturing and maintenance. When user needs change, the number of supports can be replaced and increased or decreased as needed, so that the encoder has extremely high assemblability and extensibility, and can derive products of different specifications and performances.

[0010] In some technical solutions, optionally, two adjacent supports are connected into one body by bonding.

[0011] Compared with mechanical connections (such as bolt connections), bonding connections do not require additional fasteners or connectors, thereby simplifying the encoder assembly process, which helps to improve production efficiency and reduce manufacturing costs; at the same time, such a design also makes it easy to increase or decrease the number of supports.

[0012] In some technical solutions, optionally, a first conical surface is provided at the edge of the first end, and a second conical surface is provided at the edge of the second end; the second conical surface of one of the two adjacent supports contacts the first conical surface of the other support.

[0013] By setting the first conical surface and the second conical surface, when stacking, the conical surfaces of two adjacent supports are in contact, thereby naturally guiding the supports to adjust their positions along the inclination direction of the conical surfaces, so that they can quickly find the axis and align themselves, thereby ensuring the accuracy and stability of the supports during the stacking process; at the same time, such a design also simplifies the assembly process, so that the operator does not need to perform complicated adjustments or calibrations, and only needs to align the supports and gently apply pressure to achieve fast and accurate assembly.

[0014] In some technical solutions, optionally, the main shaft hole and the support are coaxial. In this way, the code disc can be installed on the main shaft more easily, greatly improving the installation efficiency.

[0015] In this way, during installation, through the guidance of the first conical surface and the second conical surface, the two adjacent supports can quickly find their own axis and align, and when the supports are aligned, the spindle holes are also aligned synchronously, which can further simplify the assembly process. The operator does not need to perform complicated adjustments or calibrations. He only needs to align the supports and gently apply pressure to achieve fast and accurate assembly, which helps to improve installation efficiency.

[0016] In some technical solutions, optionally, an opening is provided on the code disc, and the main shaft passes through the opening and is coaxially connected to the code disc.

[0017] In the above technical solution, an opening is provided on the code disc, so that the code disc is in a C shape as a whole. During assembly, the main shaft can pass through the opening and be coaxially connected to the code disc. In this way, the code disc can be more easily installed on the main shaft, greatly improving the installation efficiency.

[0018] In some technical solutions, optionally, a mounting slot is provided on the main shaft; and the code disc is arranged at the mounting slot.

[0019] In the above technical solution, the mounting slot can provide a precise positioning point for the code disc during the installation process, thereby helping to improve the connection strength between the code disc and the spindle and reduce the risk of the code disc loosening due to vibration or impact.

[0020] In some technical solutions, optionally, the mounting groove is an annular groove, and / or there are multiple mounting grooves, and the multiple mounting grooves are arranged at intervals along the axial direction of the main shaft.

[0021] The design of the annular groove can provide a larger contact area, thereby further improving the stability of the connection; at the same time, the design of the annular groove allows the code disc to be installed from any angle during installation, making the installation of the code disc easier. Furthermore, multiple installation slots are arranged at intervals along the axial direction of the main shaft. This design provides more installation position options for the code disc. During installation, the position of the code disc can be flexibly adjusted according to specific needs to meet different specifications and performance requirements.

[0022] According to the second aspect of the present application, the present application also proposes a motor, comprising: a main body, the main body including an encoder mounting surface; a motor shaft connected to the main body; and an encoder as proposed in any of the above technical solutions. The motor shaft is also connected to the main shaft, and the housing and the encoder mounting surface are in contact. Therefore, the motor has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0023] In some technical solutions, optionally, the motor also includes a connector, which connects the motor shaft and the main shaft.

[0024] According to the third aspect of the present application, the present application further proposes an automation device, comprising: the encoder proposed in the first aspect of the present application, and / or the motor proposed in the second aspect of the present application. Therefore, the automation device has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0038] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0040] Combine the following Figures 1 to 8 , the encoder, motor and automation equipment provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0041] Reference Figure 1 and Figure 7 In an embodiment of the present application, an encoder 10 is provided, the structure of which includes a housing 100 , a spindle 110 and a measuring component 120 .

[0042] Reference Figure 1 and Figure 8 Specifically, the housing 100 includes at least three supports 101, which are stacked in sequence. The support 101 has a first end 1011, a second end 1012 and a receiving cavity 1013; the first end 1011 and the second end 1012 are arranged along the stacking direction of the support 101 ( Figure 1 The first end portion 1011 is recessed inwardly to form a receiving cavity 1013, and the second end portion 1012 is provided with a main shaft hole 1014 that penetrates the support 101 along the stacking direction.

[0043] The spindle 110 is inserted into the spindle hole 1014. The measuring assembly 120 includes a code disc 121, a light source 122, and a photosensitive chip 123. The code disc 121, the light source 122, and the photosensitive chip 123 are respectively arranged in three accommodating cavities 1013, that is, they are independently arranged in three supports 101; the code disc 121 is coaxially connected to the spindle 110, and rotates with the rotation of the spindle 110; the light source 122 is arranged on one side of the code disc 121; and the photosensitive chip 123 is arranged on the side of the code disc 121 away from the light source 122.

[0044] In the above embodiment, at least three supports 101 are stacked in sequence to form a shell 100, and the code disk 121, the light source 122 and the photosensitive chip 123 are respectively arranged on the three supports 101, that is, a modular installation method, so that the entire encoder 10 can be installed in the form of loose parts. This installation method not only simplifies the assembly process of the encoder, but also makes the encoder more convenient during manufacturing and maintenance. When user needs change, the number of supports 101 can be replaced and increased or decreased as needed, so that the encoder has extremely high assemblability and extensibility, and can derive products of different specifications and performances.

[0045] In some embodiments, there are four supports 101 , and the code disk 121 , the light source 122 , and the photosensitive chip 123 are respectively arranged in the three supports 101 in the lower layer, and one end of the main shaft 110 passes through the three supports 101 in the lower layer and extends into the support 101 in the uppermost layer.

[0046] In some embodiments, two adjacent supports 101 are connected into one piece by bonding. Compared with mechanical connection (such as bolt connection), bonding connection does not require additional fasteners or connectors, thereby simplifying the assembly process of the encoder, thereby helping to improve production efficiency and reduce manufacturing costs; at the same time, such a design also facilitates increasing or decreasing the number of supports 101.

[0047] Reference Figure 1 and Figure 4 In some embodiments, a first conical surface 1015 is provided at the edge of the first end 1011, and a second conical surface 1016 is provided at the edge of the second end 1012. The first conical surface 1015 of one of the two adjacent supports 101 contacts the second conical surface 1016 of the other support 101.

[0048] In the above embodiment, by providing the first conical surface 1015 and the second conical surface 1016, when stacked, the conical surfaces of two adjacent supports 101 contact each other, thereby naturally guiding the supports 101 to adjust their positions along the inclined direction of the conical surfaces, thereby achieving rapid self-centering and alignment (such as Figure 4 At the same time, this design simplifies the assembly process, so that the operator does not need to perform complicated adjustments or calibrations, but only needs to align the support 101 and gently apply pressure to achieve fast and accurate assembly.

[0049] In practical applications, the spindle hole 1014 and the support 101 are coaxially arranged. In this way, during installation, two adjacent supports 101 can quickly find their own axis and align through the guidance of the first conical surface 1015 and the second conical surface 1016, and when the supports 101 are aligned, the spindle holes 1014 are also aligned synchronously, which can further simplify the assembly process, so that the operator does not need to perform complicated adjustments or calibrations, and only needs to align the supports 101 and gently apply pressure to achieve fast and accurate assembly, thereby helping to improve installation efficiency.

[0050] Reference Figure 5 In some embodiments, the code disc 121 is provided with an opening 1211, so that the code disc 121 is C-shaped as a whole. During assembly, the spindle 110 can pass through the opening 1211 and be coaxially connected to the code disc 121. In this way, the code disc 121 can be more easily installed on the spindle 110, greatly improving the installation efficiency.

[0051] In practical applications, the code disc 121 is bonded to the main shaft 110. However, it is understandable that the code disc 121 and the main shaft 110 can also be connected by bolts, rivets and other structures, and this embodiment is not limited thereto.

[0052] Reference Figure 2 and Figure 3 In the above embodiment, in order to further improve the stability of the connection between the code disc 121 and the spindle 110, a mounting slot 111 is provided on the spindle 110. The mounting slot 111 can provide a precise positioning point for the code disc 121 during the installation process, thereby helping to improve the connection strength between the code disc 121 and the spindle 110 and reduce the risk of loosening of the code disc 121 due to vibration or impact.

[0053] In practical applications, the mounting slot 111 is an annular slot. The design of the annular slot can provide a larger contact area, thereby further improving the stability of the connection; at the same time, the design of the annular slot allows the code disc 121 to be installed from any angle, making the installation of the code disc 121 easier.

[0054] In some embodiments, there are multiple mounting slots 111, and the multiple mounting slots 111 are arranged along the axial direction of the main shaft ( Figure 2 Such a design provides more installation position options for the code disk 121. During installation, the position of the code disk 121 can be flexibly adjusted according to specific needs to meet different specifications and performance requirements.

[0055] It is understandable that, in actual applications, the plurality of mounting slots 111 may be arranged at equal intervals or at unequal intervals according to actual needs and design requirements.

[0056] In some embodiments, the measuring assembly 120 further includes a mounting plate 124, the mounting plate 124 is connected to the spindle 110, and the code disc 121 is bonded to the mounting plate 124. By introducing the mounting plate 124, it is possible to ensure that the code disc 121 has sufficient strength and rigidity, thereby preventing the code disc 121 from being deformed or damaged during use.

[0057] In practical applications, the code disc 121 and the mounting plate 124 may also be connected by bolts, rivets or other structures, but the present embodiment is not limited thereto.

[0058] Reference Figure 5 and Figure 6 In actual application, a notch 1241 is provided on the mounting plate 124, so that the mounting plate 124 is in a C-shape as a whole. During assembly, the spindle 110 can pass through the notch 1241 and connect with the mounting plate 124. In this way, the mounting plate 124 can be more easily installed on the spindle 110, greatly improving the installation efficiency.

[0059] In practical applications, the mounting plate 124 can be mounted at the mounting slot 111. The code disc 121 can be a circular code disc or a C-shaped code disc. When the code disc 121 is a circular code disc, a through hole coaxial with the code disc 121 is provided on the code disc 121, and the aperture of the through hole is larger than the diameter of the spindle 110, so that the code disc 121 can be sleeved on the spindle 110.

[0060] Reference Figure 7 and Figure 8 In some embodiments, the present application further provides a motor 20, comprising a main body 200, a motor shaft 210 and an encoder 10 provided in any of the above embodiments. The main body 200 includes an encoder mounting surface 201, and is fitted with the housing 100. The motor shaft 210 is connected to the main body 200 and to the spindle 110 to drive the spindle 110 to rotate. Therefore, the motor 20 has all the beneficial effects of any of the above embodiments, which will not be repeated here.

[0061] In the above embodiment, the motor shaft 210 and the main shaft 110 are connected via the connector 220. The connector 220 facilitates installation and maintenance, thereby helping to improve installation efficiency.

[0062] In some embodiments, the present application further provides an automation device, which includes the encoder 10 provided in any of the above embodiments, and / or the motor 20 provided in any of the above embodiments. Therefore, the automation device has all the beneficial effects of any of the above embodiments, which will not be repeated here.
